Abstract: Disclosed is a multi-dimensional optical tweezers calibration device based on electric field quantity calibration and a method thereof. The polarization-dependent characteristics of a tightly focused optical trap are utilized to realize triaxial electric field force calibration of particles through a one-dimensional electric field quantity calibration device. The method of the present application enables a particle electric field force calibration system to be compatible with particle delivery and particle detection systems; the device is simplified and calibration complexity is reduced.

Abstract: A device for measuring and calibrating the ground pressure of the seeding depth limiting wheels includes: a main body, connected to a pair of depth limiting wheels; a pressure adjusting member, arranged on the main body and configured to adjust a pressure of the depth limiting wheels to ground; a pressure sensor, arranged on the main body and configured to detect an actual pressure output by the pressure adjusting member; and a pressure acquisition calibrator, configured to detect a ground pressure applied by the depth limiting wheels on ground; and automatically fit a plurality of actual pressures and a plurality of ground pressures to establish a model for measuring ground pressure of a pair of depth limiting wheels. The device can automatically acquire a plurality of actual pressures and a plurality of ground pressures to establish a model for measuring ground pressure of a pair of depth limiting wheels.
